Recap 48-482
#1

Greetings all-

A couple of weeks ago I purchased a 48-482 in pretty fair shape. Initially, it would pull in the local AM station, but that was all. I started by cleaning the tuner, switches and pots. I tested it after I put it all back together, and to my surprise, everything was worse. There was so much noise in everything, I couldn't hear any stations. Then, over the next few days, it slowly got better. I could pick up the local FM station, with no external antenna. I was able to pick up several Shortwave stations. And the AM, wow. It was great. I spent some time and dialed in the presets. Then, as suddenly as it started working, it went back to all noise again. Last night, I pulled the chassis out and re-cleaned everything, including the tube sockets this time. While I had it out, I checked voltages at the test points shown on the service literature. Everything was way out of spec. So, I guess my question is would recapping take care of my problems? The reason I ask is I didn't think that bad capacitors would give an intermittent problem. Also, what all is involved in recapping? Could someone explain it, or point me in the right direction of where to find info about it? I can solder a little bit, but that is about the extent of my electronic knowledge. Any help will be greatly appreciated.

Thanks!!!
Tim
